How the data is joined

Source model and interpretation

The matrix identifies one or more Section 18 references in column B and one or more SRVs in column C. Where a row lists several references, this page uses the PDF section owner to select the reference for the current SRV. A single reference explicitly listed with several SRVs is treated as applying to each of those SRVs. Only profiles marked x are displayed below; the complete source status remains preserved in the generated data.

Update Device Configuration (Load Limiting General Settings)

18.37a · Where the target SMETS1 ESME does not support Load Limit Power Threshold (with its SMETS1 meaning) at a resolution greater than tens of Watts, the S1SP shall divide the LoadLimitPowerThreshold (with its DUIS meaning) by 10, round down to the nearest whole number of tens of Watts and set the resulting value on the Device.

Update Device Configuration (Load Limiting General Settings)

18.37e · Where the target SMETS1 ESME does not support setting of the LoadLimitPeriod or the LoadLimitRestorationPeriod (with their DUIS meanings) the S1SP shall discard the values in LoadLimitPeriod and LoadLimitRestorationPeriod (with their DUIS meanings) when processing the Service Request. For clarity, the S1SP shall create a SMETS1 Response indicating success where all other processing succeeds.
